Yes, I updated the docs.

Since the two arguments are equal, it doesn't matter which of LHS or
RHS we return.

The change I made was:

  argv += 2;

  if (*argv == NULL)
    {
      if (lhs == rhs)
        {
          char buf[INTSTR_LENGTH+1];
          sprintf (buf, "%ld", lhs);
          o = variable_buffer_output(o, buf, strlen (buf));
        }
      return o;
    }

However, now that I think about it I need to change the code more: we
need to be using "long long" here not just "long".  While on Linux etc.
a "long" is 8 bytes, on Windows "long" is only 4 bytes.
